Hi Papillon, Congrats on your 20th anniversary.
You only need to hire a Disney photographer if you want Pics in any of the parks. With that being said, you can only choose one park. You will receive 20 4x6 prints in a leather bound album. I think you also receive the rest of your proofs as well, (you'll have to check on that) As of 2004, the price was $295 and does not include Park admission.
You may also do this photo shoot at one of the resorts as well and you will get the same thing.
However, if you choose to do the photo shoot at one of the resorts, you may get more for your money if you look for an outside photographer. I would reccomend Randy Chapman. Several ladies have used him for wedding pictures and they turned out wonderful.
If you do choose to go with Disney, I would strongly suggest making a list of the shots that you want. Maybe scope out the locations ahead of time. (My experience with Disney photography has been that they want to put their time in and then leave, Now that was just MY photographer, I am sure there are others out there that are different)
To set something up with Disney, you can call Stephanie Sharpe at (407) 827-1578
or you can email her at

Hope that helps and let us know what you choose.
